There's a pledge to create a Green Homes Tax Credit, which would allow Canadians to recoup 20 per cent of what they spend to make their homes more energy efficient, up to a maximum of $3,800. And a vow to tax made-in-Canada climate-friendly inventions at a lower rate in order to spur research and development. The Tories are also committing to improving conservation funding and coming up with better ways to manage wetlands and other habitats.

And some of the other measures that the document envisions — like doing away with the carbon tax and new fuel standards, changing the threshold for large emitters and promoting the export of more Canadian oil and gas — seem destined to increase GHG emissions.

Canada has committed to cutting its national emissions by 30 per cent below 2005 levels by 2030: 513 megatonnes of carbon dioxide equivalent (Mt CO2 eq).

As of the latest federal update in December, the country is on track to reduce projected emissions by 199 megatonnes, but remains 79 megatonnes short of the goal under the best case scenario. (The gap could be smaller given that some announced carbon-reduction policies have yet to be included in the projections.)

The decrease to date has largely come from the electricity-generating sector, more specifically from the shuttering of coal-fired power plants. The oil and gas and transportation sectors remain our biggest carbon producers, collectively responsible for 52 per cent of total emissions in 2017.

A recent analysis of the Conservative plan, prepared by an economist and an environmental engineer for Clean Prosperity, an organization that supports "market-based" responses to climate change, concluded that Scheer's approach would end up being more costly and less effective than current government policies.

"Our analysis of the emissions reductions potential of the plan demonstrates that it does not have a reasonable chance of achieving Canada's 2030 target under the Paris Agreement," the authors wrote.

And while some of the Conservatives' proposed measures, like the home renovation tax credit, could have a positive effect, any emission reductions would be more than offset by other parts of Scheer's plan, they say.

"The plan would result in Canada missing the Paris target of 513 Mt in 2030 by 109 Mt, an increase of 30 Mt, or 38 per cent, from the current 2030 projection from Environment and Climate Change Canada," the analysis says.

A Real Plan to Protect our Environment talks about taking "new approaches" to reducing global emissions, such as making Canadian oil and gas the cleanest in the world and using it to replace "dirtier products" in the international market, as well as exporting more Canadian aluminum to displace metals that have a "higher emissions profile."

The theory is that Canada might then claim the relative emission reductions as a way to meet its Paris goals. But that would require renegotiating international climate agreements, an idea that Canada tried — and failed — to advance during the Kyoto talks almost 20 years ago.

It's true, as the Tories note, that Canada was responsible for just 1.6 per cent of global GHG emissions in 2014. But that was still enough to rank the country ninth in the world; on a per capita basis, Canada's 37 million people produce more carbon than any other G20 nation.

So is the Scheer plan Canada's "best" shot at meeting its Paris commitments? Quite the opposite, say observers.

"What we're seeing in this proposal is a dismantling of two of our biggest measures under Canada's climate plan — putting a price on pollution and implementing a clean fuel standard," said Isabelle Turcotte, director of federal policy for the Pembina Institute, an environmental think-tank focused on clean energy.
